Percent and Discount Shop: Shade, Save and Find the Price

Local Calculation · Private

Paying 85% is 15% off, not 85% off, and finding the original price needs division. Shop a few times and these classic grade-6 traps make sense. (For a quick real-life discount calculator, use the Discount Calculator.)

Curriculum unit

Primary maths, grade 6: the meaning of percent, percents of amounts, discounts and original prices (PEP textbook, grade 6 percent units).

For parents and teachers

Mistakes are grouped as paid/saved mix-ups, multiplying instead of dividing for the original price and confusing the sale price with the saving.

FAQ

What does 15% off mean?
You pay 85% of the original price and save 15%.
How do I find the original price from the sale price?
Divide by the percent you pay: after 10% off the price is ¥180, so the original is 180 ÷ 90% = ¥200.
Is 20% off better than ¥20 off every ¥100?
Work it out: on ¥150, 20% off costs ¥120 while ¥20 off every ¥100 costs ¥130, but the answer can change with the price.
